# Slackware build script for frotz

# Originally written for Slackware 12.2 by Beej Jorgensen <email
# removed>, heavily modified by B. Watson <urchlay@slackware.uk> since
# then.

# Original had no license. This modified version is released under the
# WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# 20230330 bkw: upstream download file changed. In case you're
# wondering, it's a one-line change in the Makefile (an extra
# digit in the git has), which doesn't actually affect the
# compiled binaries. updated md5sum in .info, did not bump BUILD.

# 20220613 bkw: updated for v2.54.

# 20211007 bkw:
# - updated for v2.53.
# - add optional xfrotz.
# - expand README.
# - make slack-desc reflect build options (libmodplug and xfrotz).

# 20210215 bkw: fix building without libmodplug. BUILD=2.

# 20201212 bkw: too many changes, can't build older versions.
# - updated for v2.52.
# - new homepage.
# - include sfrotz if sdl2 and SDL2_mixer are installed.
# - fix man page typos.
# - patch to prevent sfrotz crashes with long pathnames.
# - add desktop stuff.

# 20150904 bkw: updated for frotz 2.44.

# 20121216 bkw:
# - updated for Slackware 14 and frotz 2.43d.
# - include dumb terminal frotz in build.
